I was looking at 3D-Printsolutions' SV08 Lightweight Toolhead Mod (LTM) and thought I could keep from extending all the original toolhead wires if I mounted the board as close to the original position as possible. The StealthProtoXtruder 2.0 and it's low polygon face gave me plenty of room to add my changes, so here we are.
All the original cables are usable as is with no changes required (new extruder motor needs a specific connector, see below).
There are holes to zip tie cables to the support arm.
Printing Instructions:
I recommend VORON standards (4-5 walls and top/bottom with at least 40% infill).
Print it face down WITH SUPPORTS! This preserves the most important parts (the extruder gear areas) as they are meant to be printed. The front will look ugly, but once you put everything on it you can barely see it.
PRINTER CHANGES:
The only change for this extruder from stock is the rotation_distance in printer.cfg:
#rotation_distance: 6.5 # mm of filament per full extruder gear rotation (Original toolhead/extruder)
rotation_distance: 5.6 # NEMA 14 with Protoxtruder 2.0I used this NEMA 14 motor: https://www.amazon.com/dp/B09GKWFZSG
(3 of the 4 wires had the same colors and they matched from one connector to the other)
I used this HGX 2.0 gears kit: https://www.amazon.com/dp/B0FD3ZWTT3
I used these connectors: https://www.amazon.com/dp/B0D14Y3D8L
I used this crimper: https://www.amazon.com/dp/B078WPT5M1
Get a magnifying glass and tweezers. These connectors are teeny.
Existing problems to be fixed IMO:
ECAS04 collet: This is the first time I've used them. It doesn't feel like it sits securely in the model. Not sure if that is a problem I created when editing or if that is common to those collets, but I intend to add a better PTFE tube support. Probably integrating it into the wiring support arm. That means creating a way to get the M3 insert for the idler arm through that area. I'll figure it out. Edit: I've had a 12 hour print going and the collet hasn't popped out yet. I've got my PTFE tube zip-tied to the wiring harness and they're both hanging in there like dudes 10 bars into a pub crawl. Maybe this is just me showing my bias for threaded PC4 connectors...
I'm including the FreeCAD file with the model for those who want to experiment. I'm still new to the software so feedback/mercy is welcome.
